Anyone else facing the same problem? Seems to have started after the MacOS 26 upgrade: both when on power or on battery, closing the lid and allowing the machine to go to sleep mode, it then does not wake up and a restart is needed. Interestingly, the caps lock led seems to work, i.e. keyboard is responding, but screen remains black!

Sequoia changed how the lid sensor (magnet + Hall effect sensor) reports its state to macOS which is the reason for the error. Putting this into my terminal helped :)
sudo pmset -a disablesleep 0
sudo pmset -a sleep 5
sudo pmset -a lidwake 0
sudo killall -9 powerd
sleep 3
sudo pmset sleepnow
+1 for me on this issue. Getting it on my intel-based 2019 Macbook Pro.
Again, never had an issue like this apart from after upgrading to Tahoe.
thx your terminal commands solved the problem here

Where is the fix???
Somewhere in Cupertino… they are hiding it from us.
This works! TY
Still not working for me sometimes, even after update. So frustrating.
Ce faci?
Unfortunately the problem remains also for me, even after the 26.1 upgrade and despite having tried several "tricks" (including the suggested here reinstall, as well as the set of pmset commands suggested.
It does not happen (I think!) if I keep the laptop on power! But it does happen when on battery, after the lid remains closed for a significant amount of time. A few times, the screen did wake up after many seconds (I just happened to walk away from the laptop and come back half a minute later, to see the screen awake). However, most times, I either don't have patience to wait or it simply does not wake up even after a minute or so.
Then, it is hard reset!
Overall, really disappointing that a patch has still not be defined, to correct this! First time that I am really not happy with Apple! This has been going on for too long now!
Just for reference, the machine is a 14 in MacBook M1 Pro (2021)
